Correct. We will catch this feature soon.
You do not need to worry about the switch binding. You can specify the circuit model for the short switch using OpenFPGA's architecture description language:
@tangxifan Yep, i indeed did that as what you said , but the following description may incur problems as mentioned in https://github.com/lnis-uofu/OpenFPGA/issues/1174#issuecomment-1562196049, i.e. resulting the inconsistent between the fabric generated by OpenFPGA and the routing resource graph generated by origin VPR.
<direct name="adder_carry" circuit_model_name="direct_interc" type="column" x_dir="positive" y_dir="positive"/>
As my architecture file had the following content, especially the short type switch named adder_chain_wire, i needed to bind the switch to physical circuit. However, to my knowledge, OpenFPGA just supports mux type switch and direct connection in the directlist tag. Is there any helpful information? Thanks!
